▎ 摘　　要

NOVELTY - Preparing nano-titanium oxide-graphene oxide composite material comprises dissolving solid graphene oxide in deionized water and anhydrous ethanol, carrying out ultrasonic treatment for 30-90 minutes, adding titanium dioxide, stirring for 1-3 hours, uniformly mixing, to obtain suspension, carrying out reaction of suspension at 100-120 degrees C for 1-3 hours, filtering and carrying out air-dry, to obtain nano-titanium oxide-graphene oxide composite material. USE - The nano-titanium oxide-graphene oxide composite material is useful for absorbing cationic dye, anionic dye and non-ionic dye (claimed). ADVANTAGE - The nano-titanium oxide-graphene oxide composite material has high specific surface area and high photocatalytic efficiency. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for nano-titanium oxide-graphene oxide composite material, prepared as mentioned above.
